Prusa i3 MkII Extruder Fan Filter Cage

prusaprinters

<p>This is a filter cage that fits the 50mm x 50mm x 15mm horizontal flow fan that the Prusa i3 MkII has. I was tired of having to clean the fan blades as often as I did (I have cats - and a dusty house apparently) so I designed this cage so I could wrap some filter material around it and catch the big stuff.</p> <p>After using it a month, I must say that it works well. It stops the cat hair and larger bits, but the talc type dust still goes through (this is not surprising since I am using pretty coarse 3/16" thick filter material from <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a> )but it catches a lot. There is enough foam in that sheet to make, oh like 50 foam rings for this. It'll last forever - if you don't lose it. I used some CA glue that I had laying around to fuse the ends of the foam strip together.</p> <p>Anyway, I wanted to make it without using supports, and since I have a soldering iron I can dial down to 210C, I just made the two halves so that I could melt the ends of the rods to hold the two pieces together.</p> <p>The holes are intentionally undersized so that I could use an X-Acto blade to carve out a little at a time so they would be press fit over the SHCS so I could just press it on and pull it off without tools. It has never come off unintentionally.</p> <p>I left it hairy and dusty in the photos so you could see how well it works. That is after two weeks of printing ~8-10 hours a day.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Prusa Mk2</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>100%</p></div> </p></p></p> Category: 3D Printer Parts
